WINDOW-LOCK.

Specification of Letterslatent.

Torsion.

To all whom t may concern:

Be `it known that I, OSCAR A. Nomine, a subject of the Czar Aof Russia, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window- Locks; and I do hereby Ldeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichjit `appertalns to make and use the same.

This invention relates to new and useful improvements in window locks and the principal object of the invention 1s to provide a device which is capable of being readily applied to windows of the ordinary type without changing the construction thereof.

Another object of the invention is to provide a lock which will hold the windows in various adjusted positions and which will also hold the upper and lower sashes against independent relative movement.

A further object of the invention is to provide a device which will effectively lock the windows open so as to allow for ventilation and still prevent the same from being opened wider.

A further and more specific object of the invention is to provide a lock capable of locking the upper and lower sashes as well as the entire window in any position.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will loe fully set forth in the following specification and accompanying drawings, 1n which Figure 1 is a fragmentary view of a window partially in section, illustrating this improved lock applied thereto. Fig. 2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 is a perspective view of the keeper bar, and Fig. 4 is a view illustrating the key.

Referring now to the drawings by characters of reference, the numeral 1 designates the central or upper bar of the lower sash, while the numeral 2 designates the side bar of the upper sash. Secured to the side bar 2 is the keeper plate or bar 3, which is best illustrated in Fig. 3 and comprises theelongated rectangular body 4 provided at each end with the angular extensions 5 and the ears 6, which are formed with screw receiving openings 7, by which theV device is attached to the sashV or frame of the window.

Application filed September 11, 1915. Serial No. 50,226.

A plurality of spaced apertures 8 are form-ed at intervals in the body 4 and through these apertures extends a locking pin, which will be more fully hereinafter described. It is to be understood that the same construction of bar is used on the stop 9 of the window casing as indicated.

The lock structure, which is carried by the upper or mid-rail 1 of the lower' sash, is generically indicated by the numeral 10 and it includes a housing 11, which is attached to the upper rail l in any suitable manner. The housing 10 is provided with openings 12 and 13 formed in its walls, which openings are disposed at right angles to each other. The opening 12 faces the side rail 2 of the upper sash and the opening 13 faces the stop 9 of the window frame. Ears 14 and 15 are formed upon the walls 1.6 and 17 of the casing 11, and they are provided with openings 18, extending therethrough. Locking bolts 19 and 20 are slidably carried by the ears 14 and 15 respectively. The locking bolt 19, which has its locking end 21 projecting outwardly through the opening 12, is also slidably mounted within a guide-way 22 formed within the housing 11 and extending inwardly from the opening 12. An ear 23 is formed upon the wall 16, and extends inwardly parallel to the ear 14. A spiral spring 24 is coiled about the locking bolt 19 and one end of the spring engages a collar 24a which is mounted upon the bolt 19 and abuts the inner end of the sleeve 22, while the other end engages the ear 23, tending to force the locking bolt 19 outwardly at all times.

The reduced end 25 of the locking bolt 19 is slidably carried by the plate or ear 14, and it has a head 26 formed upon its terminal, which is provided for limiting the forward sliding movement of the bolt 19. The bolt 19 further has a projection 27 formed thereon. The projection 27 is provided for being engaged by the key indicated at 28, which is inserted through a key hole 29 formed in the outer surface 30 of the housing or casing 11, for forcing the locking bolt inwardly out of a locking position, and moving its outer locking end 21, out of one of the recesses 8, which is formed in the keeper 3.

The locking bolt 2() is identical in construction to the locking bolt 19, and it has a projection 32 formed thereon, which is adapted for engagement by the key 28 for moving the locking bolts 20 out of a locking position with respect to the keeper 3, which is carried by the stop 9 of the Window frame.

The cover 30 of the housing or casing l1,

is removably mounted upon the casing and is held in place, by means of screws or analogous devices indicated at 33.

F rom the foregoing description taken in connection With the accompanying drawings the advantages of construction and of the method of operation of the improved Window lock will be readily apparent to those skilled in the art to which this invention appertains and, While in the foregoing description, the principle of the operation o-f this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement Vof parts may be altered to suit practical conditions provided such alterations are comprehended Within the scope of What is claimed. l

That is claimed is In a Window lock structure, the combinaytion With a Window structure including upper and lower sashes, and a frame carried stop, of a keeper carried by one of the side rails of said upper sash, said keeper being provided With a plurality of spaced locking bolt receiving openings, a second keeper car'- ried by said stop, said second named keeper being provided With a plurality of locking bolt receiving openings, a locking structure carried by the upper rail of said lower sash, said locking structure including a housing, a plurality of ears extending inwardly from the Walls of said housing,

sleeves formed upon and extending inwardlyv from the Walls of said housing, locking bolts slidably carried by said ears and said sleeves and positioned substantially at right angles With respect to each other, spiral springs coiled about said locking bolts for normally holding them in a locking position, projections formed upon said 'locking Vbolts and in presence of two Witnesses.
